PAPER MILK-BOTTLE OR OTHER CONTAINER.

Original application filed December 1, 1911, Serial No. 663,197.

To all whom it may concern:

Be it known that 1, JOHN R. VAN WoRMER, a citizen of the United Statesof America, and resident of Toledo, Lucas county, Ohio, have invented acertain new and useful Improvement in Paper Milk-Bottles. or otherContainers, of which the following is a specification.

My invention relates to the manufacture of containers in general, butmore particularly to containers or receptacles made of paper, and moreespecially to those that are adapted for use as milk bottles.

This is a division of my pending application, Serial Number 663,197,filed December 1st, 1911.

Generally stated, the object of my invention is to provide a paperbottle, for milk or other liquids, of improved and highly efficient formand construction.

A special object is to provide a construction whereby a practical andefiicient method of manufacture may be employed for making said bottle.

Another object is to provide a bottle of this character having a mouthor opening which can be easily and effectively sealed after the bottleis filled with milk or other liquids.

Another object is to provide an arrangement of flaps for the top andbottom walls of the bottle, which will render the same strong andsatisfactory in character.

The nature and advantages of my improved bottle will, however,hereinafter more fully appear.

In the accompanying drawings, Figure 1b is a perspective of a papercontainer or milk bottle of the kind produced by my improved process.Fig. 2 is a perspective of the blank partially folded. Fig. 3 is adetail vertical section of the upper end of the finished bottle on line33 in Fig. 5. Fig. 4: shows the blank spread out fiat. Fig. 5 is asection on line 55 in Fig. 3. Fig. 6 is a vertical section of the bottomor lower portion of the bottle on line 66 in Fig. 7. Fig. 7 is avertical section on line 7-7 in Fig. 6.

As thus illustrated, the blank A has four parallel score lines a, a aand a? which divide the blank into five sections 1, 2, 3, 4, and 5. Thesections 1 and 3 have theinends provided with long and short flaps'ti,7,8,

punched at the same time, or afterward if desired. The flaps 8 and 9 arethen folded inward, and the flaps 12 and.13 are then folded upon eachother, thus forming a three-ply bottom. Afterward, the bottle thus madeis'treated inside and out with paraffin or the like. I

In this way I am enabled to produce a square paper container having asmall or restricted mouth and adapted for use as a milk bottle. As themouth or opening is comparatively small, it is practical and possible toseal it effectively, in any suitable manner, after the bottle has beenfilled with 'milk or other liquid. Thus a perfect and inexpensive bottleis made from a single paper blank.

The form of the blank shown economizes the paper, as there is less wastewhen the blank is cut with the long flaps at one edge opposite the shortflaps at the other edge. In fact, the cutting of the flaps, in themanner shown, does not produce any waste at all. Also, it is practicalto cut blanks of this kind by machinery.

As shown, the top and bottom are each formed by three layers glued orpasted together, whereby each end wall of the bottle is three-ply inthickness throughout the area thereof. The punching or cutting of themouth of the bottle in any suitable man ner, after the top is made,produces an openingwith a clean and true edge, which is important in thesubsequent sealing of the bottle.

As shown, the top having the hole 13' is pressed upward to make itconvex, the circular edge of the convex portion being in the plane ofthe flat surface of the top. With this formation there is a flat portionl l'beis strengthened to resist downward pressure thereon. The outwardlyconvex and in- Wardlv concave section surrounding said opening B ispreferably as large as the space will afi'ord, so that the edges of thissection extend to the upper edges of the sides of the bottle, wherebythe small flat sections 14 are separated from each other and confined tothe corners of the bottle. But as stated, the outer edges of the raisedsection practically rest on the upper edges of the side walls ofthebottle, whereby the top of the latter is better adapted to resistdownward pressure thereon. The

.top is perfectly smooth and slopes away from the hole or mouth with asurface which will not catch any liquid or material during the fillingoperation, and which can be wiped clean. Thus a thoroughly sanitarycontainer is provided.

What I claim as my invention is: 1. A paper bottle comprising arectangular body having flat sides, a flat bottom, and

a top wall provided with a round hole forming the mouth of the bottle,the said top having a raised section of which said hole is the center,said section being externally convex and internally concave, wherebysaid hole may serve as a round pouring opening for said bottle, and saidtop having corner portions disposed in a horizontal plane intersectingthe outer and lower circular edge of said section. 2. A paper bottlecomprising a rectangular body having flat sides, a fiat bottom, and atop wall provided with a round hole forming the mouth of the bottle, thesaid top having a raised section of which said hole is the center, saidsection extending to the sive With the area of said top, and theuppermost layer of the top being of one piece to provide an unbrokenouter surface and edge around said hole.

3. A paper bottle comprising a rectangular body having fiat sides, afiat bottom, and

a top wall provided with a round hole forming the mouth of the bottle,the said top having'a raised section of which said hole is the center,said section being externally convex and internally concave, wherebysaid hole may serve as a round pouring opening for said bottle and saidtop havlng cornerportions disposed in a horizontal plane intersectingthe outer and lower circular edge of said section, the top and bottombeing each composed of three layers of sheet material, each layer beingintegral with the sides and coextensive with the area of the top orbottom, and the uppermost layer of the top being of one piece to providean unbroken outer surface and edge around said hole.

4. A paper bottle blank comprising four parallel sections of uniformlength, separated at their side edges by fold lines, and long and shortflaps for the ends of said sections, the short flaps of one end beingop-- posite the long flaps .of the other end, the short flapsalternating with the long flaps at each side of the blank, each longflap being coextensive with the top or bottom of the bottle, and eachshort flap being one half the area of said top or bottom.
